Rainbow

Basically Ritchie Blackmore's solo band following his departure
from
Deep Purple
in the mid-seventies, Rainbow is also where vocalist Ronnie James
Dio first came into prominence (he was in an earlier band called
Elf, but it was here that he became well known, before moving on
to
Black Sabbath
and later his own band).
As can be seen below, a number of well-known hard rock musicians
have taken part in the band over the years.
